the only way to start a car when the remote key is dead is to start it by putting the key into the ignition.
likely explanation: dead battery, either in the car or in the remote
Sounds like a dead car battery. Do any lights or electrical accessories work?
If you are using it to turn on the car a good battery would help.
Get a donor car and use it's battery to start your car. You will need a set of quality jumper cables. Or you can charge the dead battery on the car for about 2 hours with a good 10 amp battery charger.
If your car battery is dead, you will not be able to start your vehicle without a jump using jumper cables. When the car won't start and the lights on the dash aren't working, it is most likely your battery.
No
because the remote is no longer programmed it will need reprogrammed
check if your lights are still on that drained the battery
Dead battery ?
from a dead battery to working battery
Do you mean "jump start"? If so, yes- it requires a car with a good battery, and a set of jumper cables- connected the RIGHT way between the two vehicles. With older vehicle, it was possible to "push start" the car with the dead battery- but with modern electronics, and a completely dead battery, will not work.
You can if the key has a door lock/unlock button. I lock mine all the time with the remote. If you have the button on the key and it is not working then maybe the battery in the remote is dead? Open it up and replace the battery.
